C Sowle Reservoir dam
C Sowle Reservoir
C Sowle Reservoir, located in Culbertson, Montana, is a privately owned water resource managed by the USDA NRCS. Built in 1940, this Earth-type dam stands at a height of 20 feet and has a storage capacity of 54 acre-feet, primarily serving purposes such as fire protection, stock watering, and small fish pond habitat. The dam, situated on TR-Hardscrabble Creek, is regulated by the Montana Department of Natural Resources and Conservation, ensuring proper inspection, enforcement, and permitting to maintain its integrity and safety.
With a low hazard potential and a condition assessment that is currently not rated, C Sowle Reservoir offers a reliable water source for local agricultural and wildlife needs. Despite its modest size, this reservoir plays a crucial role in the region's water management efforts, especially during times of drought or wildfire. As a key component of the local water infrastructure, maintaining and monitoring this reservoir is essential to ensuring the sustainability of the surrounding ecosystem and community.
As climate change continues to impact water resources in the area, C Sowle Reservoir serves as a vital asset for mitigating the effects of fluctuations in water availability. Its strategic location and design make it a valuable resource for supporting both human and ecological needs, highlighting the importance of responsible management and stewardship. For water resource and climate enthusiasts, C Sowle Reservoir represents a unique opportunity to study the intersection of water management, climate resilience, and ecosystem health in a dynamic and changing environment.

Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.

About C Sowle Reservoir
Where does the data for C Sowle Reservoir come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
